Verizon is showing by how much it leads the market for wireless computing by attracting iPhone customer complaints a full week before it even begins selling its version of the previously AT&T exclusive.

Verizon admitted today that some customers ran into problems yesterday trying to pre-order the phone, which is scheduled for release Feb. 9 and could sell as many as 13 million units, analysts have predicted .

iPhone 4 pre-orders were 10 times higher on the first day they were available than the first day the iPhone 3GS pre-orders were available, an AT&T spokesman said at the time.

Verizon is working on its (notoriously slow and clunky) phone-ordering web site to make sure it stays online, and so far has not run into any inventory problems with the iPhone, a spokesperson told Reuters.
